Embodiment Construction
[0049] Turning now to the drawings, FIG. 1 is a schematic cross-sectional view of a conventional inverted coplanar thin film transistor (TFT). Referring to FIG. 1, gate electrodes 11 and 51 are formed on a substrate 81, source electrodes 12 and 52 and drain electrodes 13 and 53 are formed above the gate electrodes 11 and 51, respectively, and a gate insulating layer 83 is interposed between the source electrode 12 and the gate electrode 11, between the drain electrode 13 and the gate electrode 11, between the source electrode 52 and the gate electrode 51, and between the drain electrode 53 and the gate electrode 51. A semiconductor layer 80 contacts the source electrodes 12 and 52 and the drain electrodes 13 and 53. The source electrodes 12 and 52 and the drain electrodes 13 and 53 may be interchanged.
[0050] In the above structure, the semiconductor layer 80 is not patterned but is formed as a single body for two adjacent thin film transistors (TFTs) 10 and 50. In this case, cross-...
